1 Claim.

This invention appertains to new and useful improvements in creamseparators especially adapted for milk bottle use.

The principal object of the present invention is to provide a creamseparator which can be easily handled and which will not require tiltingof the bottle in separating the cream from the milk.

Other objects and advantages of the invention will become apparent tothe reader of the following specification.

In the drawing:

Figure 1 represents a side elevational view.

Figure 2 is a fragmentary sectional View on the line 2-2 of Figure 1.

Figure 3 is a fragmentary perspective View of the upper portion of theseparator.

Referring to the drawing wherein like numerals designate like parts, itcan be seen that numeral 5 represents the cylindrical container wallwhich' has a downwardly converging bottom 6 of frustreconical shape, theextreme lower portion of which is open as at 1 and this forms a seat forthe conical-shaped valve 8, upwardly from which extends the stem 9. Thisstem 9 is threadedly engaged as at I into the valve element 8 andextends upwardly through the uppermost portion Il of the frame generallyreferred to by numeral l2, the same terminating at its upper end in thehand grip I3 between which in the portion Il of the frame is the coiledcompressible spring I4, serving tonormally maintain the valve 8 seated.

The frame l2 is of one piece construction, the same having the dependingdiverged leg members l--I 5 riveted or otherwise secured at their lowerends to the container 5 as at i6. The upper portions of the legs l5flare outwardly as at I1 and then extend back inwardly to merge withthe' frame piece Il. Thus the portions Il define finger holds which canbe used in conjunction with the handle I3 in manipulating the valve 8and lifting the container from a milk bottle, the bottle being denotedby numeral I8.`

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is vclaimed as new is:

A cream separator comprising a tubular container for insertion endwiseinto a bottle in upright position and having a tapering lower endforming a reduced aperture therein, a frustoconical valve member movableupwardly and downwardly in said aperture to close and open the same,respectively, an operating rod extending from said member upwardly outof the container and having a thumb-piece on the upper end thereof forpressing the same downwardly to correspondingly move said member, asingle piece strap metal frame extending upwardly from the container andcomprising a pair of straight side stretches converging from oppositesides of the container into engagement with opposite sides of said rodto form therebetween a lower guide for said rod, an upper cross stretchthrough which said rod is slidably extended and forming an upper guidefor the rod, and a pair of upwardly arched stretches connecting saidside stretches to said cross stretch upon opposite sides of the rod andforming inger grips for suspending said frame from the fingers, andspring means tensioning said rod against downward movement.
